' To giprevent; lateral .movement of Ithel arm I I,

-collarsifZan-dl bearing .against opposite faces oiiithearm-holdingzmemberiZZfare securedito'ft'he the arm I2, This arrangement will be described in greater detail hereinafter,

With the above described arrangement the arms II and I2 may be xed relative to each other and may be freely rotated to any desired position when the set screws I'I and 24 are loosened Without disturbing the relation of the arms to each other in any Way.

The arm II extends beyond the arm-connecting bar 2| and carries a tracing tool 3E) at its outer end. The arm I2 extends into the armholding member 22 and has a threaded portion of reduced diameter at its end on which the spindle head 29, previously mentioned, is secured.

The spindle head 29 has a fitting 3| extending at right angles to its body for securing it to the arm I2. The fitting 3| threads onto the threaded end of arm I 2 and is circular in section having at its outer end of the same diameter as the arm I2 so that it will t into the openings in the arm-holding member 22. Immediately adjacent this portion of reduced diameter there is an enlarged portion which is externally threaded on which there is a lock nut 28. The spindle head is threaded on the end of the arm I2 until its tool-holding means 32 is in exact alignment with the tracing tool 3G in the arm I I. In doing this the enlarged portion of the fitting 3| Will be brought adjacent the end of the outside of the pivoted member 22 and by tightening the lock nut 2B against the outside of the arm-holding member 22, the spindle head will be locked in place. This may be done with the spindle head in any position and the arm I2 is then rotated in the arm-holding members I5 and 22 until the axes of the tracing tool 13B and the' spindle head are parallel,

On the end of the arm I2 projecting behind the axle 4 an electric motor 33 iscarried for driving the tool carried by the spindle head 29. The electric motor 33 is mounted on a sleeve 34 which surrounds the end of the arm I2 and which is held on the arm I2 by set screws 35 and 36 Which bear against a split bushing 3.1 located inside the sleeve 34 to clamp the' motor in place on the'arm l' I2. Thus themotor 33 may be turned relative to the arm I2 so as to bring it in position corresponding Vapproximately to that in Which the spindle head 29 has been locked.

The motor 33 drives the tool carried by the spindle head ,29 through a belt 38 Which runs between a driving pulley 39 on the shaft of the motor 33, and a driven pulley 4D on one end of a shaft which drives the tool-holding means 32 0f the spindle head 23.

To counter-balancev the Weight carried by the arm I2 a counterweight 4I is carried on the end of the arm I I.

To avoid interference With the belt 38 when the spindle head 29 and the motor 33 are, for example, in a horizontal position or to permit the passage of material being Worked on, the cross bar of the arm-connecting bar 2| is raised to provide an enlarged opening beneath the cross bar at the central portion of the arm-connecting bar 2 I.

When the spindle head 22 is locked in a vertical position and a tracing tool is carried at the `outer end of the arm I I, the machine may be used as a tracing machine for duplicating Wood carving, Or the pivoted member 22 in the opening ofthe arm-connecting bar 2| may be secured against pivotal movement by inserting a` screw 424 through the arm-connecting bar 2| into the side of the member thus securing the member rigidly to the arm-connecting bar 2|. With this arrangement the machine may be used for straight routing and similar purposes as now it Will not be possible to move the arms II and I2 and the spindle head 29 laterally of the frame in a horizontal plane.

To use the machine for circular sawing, the

spindle head 29 is placed in a horizontal position by turning the arm I2 and aV circular saw 43 is secured t0 the tool holder 32.-. In this position the spindle head is supported from the frame by an arm 44 which may be adjusted to hold the spindle head at any desired height. In such instances Where the spindle head is horizontal, the screw 42 will preferably be inserted in the arm-holding members 22, as previously described, to hold the arms against lateral movement thus giving added rigidity to the noW locked pantograph mechanism of the machine.

If it is desired to operate the machine as a lathe, a dead center 45 and a tool rest 45 may be mounted on the front of the frame and the spindle head 29 will be placed in a horizontal position and secured to the frame inline With the dead center 45 by a supporting member 4'I.

The machine may be operated as a belt sander by turningr the arm I2 so that the motor 33 and the spindle head. 29 are in a horizontal position. A drum 48 is placed on the tool holder 32 of the spindle head 29 and a drum 49 is placed on a shaft extending from the motor 33. A sanding belt 53 is carried on the drums 48 and 49. Here again the mechanism is held in place on the frame by the supporting member 4T.

It will be understood that my machine may be arranged for other uses besidesthe ones speciically mentioned herein and `by mentioning these examples specically it is not intended to place limitations on my invention.
